<span>Explanation:
</span><span />
<span>When solutes dissolve in water there are two possibilities: 1) either the solute dissociate into ions (which is the case of ionic compounds) and the ions are solvated by the solvent, or 2) in the case of covalent compounds the entire molecule is solvated by the molevules of the solvent (water).
</span><span />
<span>The compound C₃H₆(OH)₂ (propylene glycol) is a covalent compound, so when dissolved in water it will not dissociate but will remain as a molecule, and that molecules is the species solvated by the molecule of water.</span>
Answer:
704.6 g CO2
Explanation:
MM sucrose = 342.3 g/mol
MM CO2 = 44.01 g/mol
g CO2 = 456.7 g sucrose x (1 mol sucrose/MM sucrose) x (12 moles CO2/1 mol sucrose) x (MM CO2/1mol CO2) = 704.6 g CO2
This reaction is known as
Acidic Cleavage of Ether.
Ether when treated with strong acid like
HI, the oxygen atom of ether picks the proton making a positive charge on oxygen. The
Iodide conjugate base formed acts as a
nucleophile and attacks on the carbon next to positive oxygen and forms
Alkyl Halide. This is a type of
SN² reaction. The complete reaction with missing atoms, charges and arrows is shown below,
1 mole Zn ---------- 6.02 x 10²³ atoms
0.750 moles Zn ----- ?
atoms = 0.750 * ( 6.02 x 10²³ / 1 )
= 4.515 x 10²³ atoms
hope this helps!
